Tim Cook may lead his final WWDC keynote as Apple CEO today

Tim Cook is expected to open Apple’s WWDC26 keynote today in what may be his final WWDC appearance as the company’s CEO. Cook is likely to follow the familiar format: introduce the event, hand off to other executives for the main software sections, and return near the end.

Apple has not announced the presenter lineup, so this is still an expectation rather than a confirmed farewell. But the timing is clear. Cook is stepping down as CEO on September 1, 2026, while hardware engineering chief John Ternus will become Apple’s next CEO.

That makes WWDC26 the last major software keynote of the Cook CEO era.

WWDC26 starts with software, not succession

The keynote begins on June 8 at 10 a.m. PDT, followed by the Platforms State of the Union at 1 p.m. PDT. WWDC26 runs through June 12 and is expected to bring updates across Apple’s platforms, including AI advancements, software features, and developer tools.

Cook has opened WWDC keynotes since 2012, but he usually gives way quickly to the executives closest to the software. AppleInsider says Craig Federighi is expected to carry much of this year’s keynote, which would fit WWDC’s usual rhythm.

It would also fit the moment. Federighi is Apple’s software chief, and WWDC26 is expected to be heavily shaped by Apple’s delayed AI work, including the long-overdue Siri reset.

Siri may define the last Cook-led WWDC

The report says Mike Rockwell, who moved from Apple Vision Pro work to managing the Siri and AI team, may introduce the new Siri experience. Other executives are also expected to handle platform-specific sections, including visionOS and watchOS.

That presenter mix matters because this WWDC is not only about who appears first on screen. Apple needs to show that its AI plans are moving from promises to real features people can use. The expected iOS 27 Siri upgrade is the centerpiece of that pressure.

If Cook does bookend the keynote, Apple may keep the succession story quiet and let the software do the talking. The company rarely turns WWDC into a personnel event, and there is no sign yet that Ternus will share the stage.

Still, the leadership handoff changes how this keynote will be read. Cook is expected to lead Apple through the summer, while Ternus’s first big moment as CEO will likely be the September iPhone event.

For viewers, the practical part remains the same: WWDC26 starts today with Apple’s biggest software preview of the year. For Apple, it may also be the final WWDC keynote with Cook as the person opening the show.
